In-"Figure ,4, I have illustrated an alternative means'for attaching such devices to the spouts.. This comprises a clip 28 that is attached to the housing "and which has paired fingers 29129f adapted to embrace the opapplied to spouts of siruppumps without requiring any change in the latter and will serve to retain the spouts closed at all times except when 'sirupis being discharged and,

in this way, they will positively prevent flies or} other. insects "from entering the spout during periods of time when the pump is not J in use and will also catch any dripthat might otherwise flow from the 'spout after use. The

devices are also automatic in their closing or opening action and it is not necessary for an operator tomanually actuate the device to 'openposition when sirup is to be discharged;
